The UFO Forwarder Trailer has been designed to hold greater volumes of wood, pulpwood, wood parts, tops and branches etc. The Forwarder Trailer increases the forwarder´s capacity and flexibility. It reduces forest damage through lower ground pressure while simultaneously minimizing fuel consumption per cubic meter of timber. The trailer is available with a mechanical of hydraulic drawbar. The hydraulic drawbar allows the trailer to be loaded and unloaded with the forwarder´s ordinary crane as the trailer is pulled in hydraulically at loading and unloading, and then pushed out while driving.
